I saw an interview with the British lady who commercialized the game (which she learned as a kid in South Afrika a long time ago) and she did specifically mention that the original game was made by hand with all the imperfections that implied. According to her some blocks almost falling out and others being pinned is the point of the game.When they mass produced the game, planing them into perfect pieces was a problem as it made the game too easy and they had to add imperfections to the blocks in the planing process so they are NOT all the same.(She and the game Jenga is profiled in season 1 episode 9 of the "Million Dollar Genius" tv show on the History Channel)
